This invention relates to devices for spreading butter, ljam or similar substances upon bread slices or the like. It is'the object of the invention to apply butter rapidly and evenly upon such slices. It is a further object of this invention to provide-means for varyingthe thickness of the butter film, applying-the butter economically without any appreciable loss. n It is another object of the invention to provide means `for an equalV distribution of butter upon bread Vslices havingV non-parallel surfaces.

lVith these and other objects in vicwwhich will become more apparent as the c escription progresses, the invention consists in a novel combination of parts and details of construction hereinafter described andillust-rated in the accompanyingdrawings ,which form a material part of this disclosure and as yiinally pointed outin the appended claims.'

This butter spreading device .is mounted upon a suitable table provided with a wide longitudinal slot which accommodates an endless conveyor belt supported at intervals upon idler rollers 18and ydriven by means of e: supporting table and conveyor belt are shown a friction pulley 21 eitherby hand or by suitable power means. .This belt and its driving means are more fully illustratedl inA myv copending application for Letters Patent for 2L machine for making sandwiches, Serial No. 199,269 .filed June 16, 1927 ,of which this but-V ter spreading device forms an important -p art. Upon table 15 to either side of belt 20 a vertical post 71 is provided. These posts arejoined to each other by'a ring or hoop l7 2 and their upper ends have vertical slotsin which trun nions 73 of a butter storagevess'el V.7 0 are Acarried. The lower part of this storage vessel has the shape of a funnel'withdelivery spout 701 y which is cut offunder an angle. The angular opening is covered by` a lid 702 which is `mounted toswing about a hinge-pin 703 held on a bracket 704 von the outside of spout 701. Lid 702 has an upward extension beyond hinge pin 703 with la threaded aperture ocr cupied by adjusting screw 705. The point of this screw presses against the conical surface of storage vessel 70. As screw 705 is loosened the lid 702 opens by gravity. .i To lower part of posts 71 hook-shaped brackets 83 are attached, these hold ltrunnions 82 andV 820 of a butter container orI fountain 76 which is rectangular in plan andhas the width of belt 20. The bottom of container 76 is slanted towards the front side which is formed by roller 77. This roller is longer than the width of the container or belt 20. The container casing is widened to accommodate the roller between the side plates 78 and the transverse front faces of the casing are curved to it the roller closely at 761. y The front edge of the slanted bottom of the container 76 is provided with a knife blade-80 which extends along the full length of the roller 77 between side plates 78. Below this knife a transverse shaft 762 is arranged which is ournalled in bearings on side plates'78. Shaft 7 62 is provided with aneccentric portion located between side plates 7 8. Knife 80 which is preferably made of resilient sheet metal leans with its lower face against shaft 7 62. A knob 763 grooved on its cylindrical surface and provided with' a dial on its frontl face serves to turn thisshaft and thel` eccentric portion on shaft 762. When knob 763 is rotated it lifts knife 80 gradually toiria wardsV the roller until the front edge of the knife leans against roller 77. An indicating spring 7 64 which engages the grooves of knob 763 indicates the size of opening between knife 80 and roller 77 and consequently the thickness of. butter-film applied thereto.

' Roller 77 is journalled on centers 771 and 7574 rthrough between thelroller ends and side Y plates l78'. 2Further'gi'it'tfers 151'1a're arranged transversely upon table V@ to collectthe drip'- pings from lgutters 781 and 'to lead Vtlier'n lto 820 :of 'container v7 6.

collecting `vvessels a'tetlie sides `of table 15. On one side'of `container'7t an upward `extensic'n 765 is provided :which Iholds azhorizontal adjusting screw 85,the point 'of' lwhich leans against a stopl 711 'on standard 71. '(See liig.2.)f

Above roller 77 parallel to its afxis and between "side plates 7 8 is )mounted a 'scraper blade791 which isb'ent downward in radial direction of th'eroller 5to alineabove-the butter filinon vvthe roller. Ttis theipurpese'of'this bladelto :prevent bread crumbs, to `becarried into the-butter of container 7 6. Such crumbs are 'sometimes separated 'from vthe lastbuttered slice andare carried bythe roller.` The rear plat-e of container 76 carries a weightwliich may be varie-d'by addition or removalof thin washers heldfthere-n. The butter spreading device 'is preferably fplaced en table "15 in 'Suche l"position that "an idler roller 1'8 lbelow Ybelt 420 vijs "a short distance 'ahead of fountain roller77. f

The roller'77 "is driven to rotate at 'the same 'speedas belt '20 see Figs. I6 'and '7) by means of a narrow beltv 300 running on a ulley 210 of the sanie diameter asp'ull'e'y 21. Belt 300 drives a pulley 301abo`ve table 1 5 arranged on shaft 302 Iand bearings 303, of the saine diameter as roller 77 Shaft 302 arranged in axial alinenient with trunnions `82`ahd y820 ofthe'container 70. 'It carries Ia clutch block f304s`lidably held thereon by a guide pin 305 which forms means( to Arotate the clutch'and'to lock it. A'Between block'304 and the adjacent bearing 303'a helical spring 306 is, 1interposed which presses 'the block away fronrthe bearing. Block 304 carries at its '"fron't end a' pin 308 fwhich enters Van aperture ofa gear' 311 niu-nted loosely upon pivot Pin 308 finay be 4disengaged from -fg'ear 311 by-'slidingblock 304 backward and pressing itagainst spring 306. 1t maybelocked lin this position bytur'ning block 304 slightlyz 'which brings pin 305 into the angularpartof's'lot 307. `Gear 311 meshes into a gear 310 of equal diameter mounted upon the Toller-*center 774. lNext to this 2 Y l 1,816,535v

center-forming point a pin 775 is provided which enters a corresponding aperture of roller 7'7 forV rotating the roller. In this manner the roller can be rotated continuously on its axis and it may simultaneously oscil@ late about trunnions 82 and 820.` The power drive` Amay be disengaged from the butter spreading device yby ."nea'ns of Eclutch block To hold the butter ata uniform consist- 'ency its Y"temperat'ure I'is regulated by means of an electric heating device L101 inserted into one of the lbutter containers, preferably the upperone- This heater consists of a resistance enclosed in a closed tube; its current 'may be switched onor off byfha'ndby a 'switch 403 or preferably by athermostat switch 402 whichfis inserted ieitherin the 'same orv in the .other 1butter container 76,.Y the latter method is shown inthe drawings. Thermo- 'static vswitches Vfor `this Vpurpose consist prefera'bly'of a flatl blade or reed of two kmetals having different'coefiicients'of expansion and Y close or open a circuit bytheir 'bending under heat action, 'the thermostatic element is enclosed ina 'tube similar tothat of the d heating element. Y The reliable operation of this `butter spreading device is obtained-as follows Container and storage vessel 76 are lilled with butter having a temperature lof about deg. F. The weight 84 at'the rear end of container :70i'sth'en so adjusted that the kfront andrea'r parts of'thefounta'in are balanced about/fthe `pivts A82 "and F820. A l

be buttered is placed below roller 77 'and screw is adjusted so that 'its pjoint 'leans against 'stop 7111 lwithout lifting 'roller 77 from Vthe bread slice. -As this screw is 'arranged above pivots 82 lits `tightening-'lifts this roller grfadually. The knife V'80 -isthen adjusted away "fromroller 77 Aby turning knob 763 topermititheroller lto be'coveied wit-ha film of butter when turne'd. ASpring i 7 64 holds k'eccentric vshaft 7 61 against. v'accident'al'ro'tation and "serves as Yanindec iin-ger for 4the thicknessofbutter film on lroller `77 in connection with the l'dialon Aknob 7 63.

Belt 20 is then'set in motion i'n'the direction lofthe arrow 'of Fig. vQ'e'ither 'by handfor by suitablemechanical'means,andslices'ofbread placed thereon in short intervals. When the front'edge ofa bread 'slice'reaches Ythe yiowestline of roller7( it-'st'arts'to"liftfthe"saine'by lui.

' slice of bread' of'thethickness"of those to not escape. As butter is dispensed, fromV fountain 76 the balance of the latter would be disturbed and the pressure of the roller 77 against the bread slices would be increased. To prevent this, and to keep the fountain constantly filled to the same level, the storage vessel 70 is provided and its lid 702 may be so ladjusted that it supplies just as much butter to the container 76 as is dispensed therefrom by roller 77.

To clean the device the power drive is first disconnected from the device by pushing clutch block 304 to the rear and giving it a slight turn to lock it. The storage vessel 7 0 is then removed by lifting its pivots 73 out of the slots in the upper endsof standards 71. The container can then be lifted up so that its pivots 82 become free of brackets 83 and adj usting screw 85 from stop 711, whereupon the j container 76 can be moved out of its place in forward direction. The roller 77 can be removed as previously described by pulling knobs 773 and gear 311 outwardly and the whole apparatus may be washed in an alkaline bath and rinsed, to remove all traces of butter.

The facility of operating and cleaning this device is one of its principal advantages. It may be continuously operated for many hours as more than one storage container can be employed, one being filled while another one is in operation.

The economy in butter consumed is another advantage as all butter not applied to the bread slices is returned to the container, and as there is practically no leakage although precautions are included in the design that no leakage can reach the belt.
